摘要
本论文主要是探讨了乳糖酶水解生鲜牛乳中乳糖的工艺。实验证明:加入 1000NLU/L和2000NLU/L乳糖酶在常温 37℃下 3h和 1.5h可将生鲜牛乳中的乳糖含量降低 50%左右,在低温 9℃下 18h和 15h也能达到同样的效果。由于乳糖被分解为葡萄糖和半乳糖,使得个乳甜度增加。
The technology of hydrolyzing lactose by lactase in balk is studied, the lactase dose is 1000 NLU/ L and 2000NLU/ L when the hydrolysis time is 3h. 1. 5h respectively at 37℃, or 18h and 15h respectively at 9℃ will hydrolyze 50% lactose in milk Because the lactose is hydrolyzed to glucose and galactose, the milk is more sweeter.
